I don't co-wash AT ALL for this reason: buildup. Conditioners always deposit more on my scalp than washes away. My scalp can't take it. Check out my sig below for a low poo solution...

And then there are so many possibilities in between strict cowashing and using shampoo for every wash: like watering down the shampoo before using it, or adding a bit of shampoo to the cowash either sometimes or often. Or "lo-poo", of course. Or just using non-sulfate shampoos (though use of a lot of conditioner and/or stylers can eventually lead to a need for a one-time clarifying sulfate shampoo).
